PANTOGRAPH.

SPECIFICATION forming part of Letters Patent No. 469,775, dated March 1,1892.

Application tiled November 2, 1891. Serial No. 410,614. (No model.)

To all whom it may concern:

Be it known that I, LOUIS COTE, of St. Hyacinthe, in the Province ofQuebec and Dominion of Canada, have invented certain new and usefulImprovements in Pantographs, of which the following, taken in connectionwith the accompanying drawings, is a specification.

My invention relates to pantographs, and has for its object theadaptation of the pantograph to use in outlining and proportioning bootand shoe patterns and drawing the same on paper or cutting the same frompaper or other suitable material.

In the manufacture of boots and shoes a great number of sizes and styleshave to be made to meet all the requirements of the various purchasers,and in order to withstand the sharp competition in the business it isnecessary that economy be exercised in the cutting of the stock, andtherefore patterns have to be made for each size and style of up per. Avery important item in the production of these patterns is the properoutlining and proportioning of all the sizesof a given style from asingle pattern, and this when done by hand by an expert draftsman is anexpensive operation. To obviate the necessity of employing such skilledlabor to do this work and to render'it practical for any intelligentworkman to produce'his own patterns, or, if desired, to cut his ownuppers, all correctly proportioned and scaled up or down from a singlepattern, is the object of my present invention; and it consists incertain novel features of construction, arrangement, and combination ofparts, which will be readily understood byret'erence to the descriptionof the drawings, and to the claims hereinafter given, and in which myinvention is clearly tional elevation, the cutting plane being on line 22 on Fig. 3 and looking toward the left of said Fig. 3. Fig. 6 is asection on line 3 3 on Fig. 3. Fig. 7 is a section on line 4 1 on Fig.3, enlarged. Fig. 8 is a plan of, another portion of the machine, drawnto an enlarged scale. Fig. 9 is a vertical section on line 5 5 on Fig. 8and showing portions of certain parts in elevation.

- In the drawings, A is a rectangular table made,preferably, of wood,which may be supported in any suitable manner at a convenient height foroperation.

B is a metal disk or plate having cut through it an open slotextending'about three-fourths of the distance across it a little to oneside of its center, the side walls of said slot being provided withinwardly-projecting lips or a, to which is fitted, so as to be movablethereon, the three-armed or T-shaped bar or plate B, to which is pivotedat a the inner end of the lever b, fulcrumed upon the pin 19', set inthe disk B. The disk B is firmly secured to the table A and has formedin its upper surface a plurality of grooves c, c, and 0 arranged atright angles to the line of movement of the bar B, and the lever b haspivoted thereto, between its fulcrum-pin and the bar B, the forked endof the handle 19 provided with the slot 12 in which is adj ustablysecured the pin b the lower end of which engages one of the slots 0, c,or 0 when the free end of the handle I) is depressed. The table A alsohas firmly secured thereto the supporting-bars A and A at the rearedgeand right-hand end, respectively, and has secured to itsuppersurface, one near each end thereof, the standards 0, the upper endsof which are connected together by the rod 0', in the under side ofwhich is formed the longitudinal groove a said rod 0 having mountedthereon, so as to be adjustable endwise thereof, the sleeve G which isprovided with the spline a to fit the groove a and the set-screw d toclamp said sleeve in position on said rod 0. The sleeve C has formedtherein a socket or bearing at right angles to but below the rod 0, inwhich is fitted, so as to bemovable endwise therein, the rod 0 havingsecured to its front end the bar G which has formed therein the slots (1d, in whichv are adjustably secured by the nuts e the clamping-bolts e eand the pendent hubs e e, to which the metal pattern C is secured bymeansof the nuts 6 6 as shown in Figs. 1, 2, 15, and 16. The three-armedbar B has formed inits upper surface the rectangular groove 0 and theinverted-T-shaped groove c arranged at right angles to the groove 0 saidgroove 0 having fitted thereto, so as to be movable endwise therein, theplate B to which ispivoted by the common fulcrum-pin d the bars D and E.The bar D has its main body fronlnear the fulcrum-pin d to its righthand end made L-shaped, and has formed in its front side the shallowlongitudinal groove f,-as shown in Figs. 9 and 12. Thehorizontal webportion of the bar D extends beyond the fulcrum-pin 01 toward the leftof Figs. 1 and 8, andhas formed therein the longitudinal slot f, inwhich is adjustably secured the stud g, upon the lower end of which ismounted the roll 9', which fits into the groove 0 in the bar B, as shownin Figs. 9 and 10. The stud g also carries the rectangular plate g oneedge of which serves as an index to assist in the proper adjustment ofthe stud in said slot, the bar D having formed therein a series ofgraduations, as shown in Fig.8. The bar D is made of suflicient lengthto rest at its free right-hand end upon the bar A by which and the bar Ait is maintained at a suitable distance above and parallel to the tableA,as shown in Figs. 1 and 2. The bar D has an oifset or bend in it nearthe fulcrum-pin (1 so that the pencil-holding sockets (to behereina'fter referred to) may extend below said bar aud'at the same timebe in line with the centers of the fulcrum-pins d and g, as shown in'Fig. 1. Thebar E is T-shaped in crosssection, the central rib beingupon its under side, as shown inFig. 4. and rests in a notch d in theradius-arm B, mounted upon and movable about the vertical stud B set inthe nected thereto by means of the two slides E and E fitted to andclamped upon said bars E and F, respectively, and pivoted together by asuitable pin, as shown in Figs. 1, 3, 4, and 5. The front end of the barF is connected by the pencil and knife socket h to the slide H, fittedto and movable endwise of the bar D, as shown in Figs. 1, 2, 3, 4, and12. The bar F has pivoted to its under side a series of bars I, I, I and1 upon which rest a series of socket-carryingbars, as G, G 3 4 5 G6 7 89 10 11 GA o o G, and G each of which is pivoted to at least two of thesupporting-bars I, I, 1 or 1 and the front' end of the bar G-isconnected by its pencil-socket to the slide H, as shown in Fig. 4. Thebars E and F are graduated, so as tofacilitate the correct adjustment ofthe slides E and E thereon.

J and J are two standards mounted upon the bars I and I above the bars GG and G and having secured to their upper ends the arm K by means of thethumb-screws j and j in. such a manner that itmay be adj usted in adirection parallel to a linedrawn through the centers of the severalpencil or knife holding sockets h, said arm having a series of holesformed therein to receive the shanks of the screwsj andj, as shown indotted lines in Fig. 3, the upper end of said standardsJ and J havingformed therein a corresponding number of threaded holes to receive thethreaded ends of said screwshanks.

The arm K has set in its front end the tubular stud 70, upon which ismounted the sleeve is, provided with a hub or shank k upon which issecured by suitable nuts the ,U-

shaped swivel it to which is pivoted the handle by which the machine ismanipulated. The stud 70 has mounted therein the spindle Z, to the upperend of which is secured t-he crank Z, having the crank-pin 1 upon whichis mounted the truck Z having formed therein a peripheral groove, thebottom of which is directly over the center of the spindle l, which inturn is directly over the center of one of the pencil-sockets or in thevertical plane cutting through the series of pencil-sockets.

In operating the instrument the truck Z is placed with its groovedperiphery in contact with the edge of the pattern 0 and kept in contacttherewith, while it is passed entirely around its perimeter.

L is a plate of glass resting upon the table A between the disk B andthe bar A and secured in position in any convenient'manner, and M M aretwoclamping-bars for holding the paper or leather in position on saidglass, said bars being providedat each end with a downwardly-projectinghook M, which engages with the lifting-bar N, secured one to the frontedge and one to the rear edge of the table A by means of the screw-studsp, which pass through oblique slots 19', cut through said barsNandscrewed into the table A, as shown in Figs. 1 and 2. Each of the IIObarsNhas formed in its upper edge near one end thereof a series ofrack-teeth arranged in a plane parallel to the center lines of the slots19, with each of which the teeth of a segment of a gear mounted upon therocker-shaft O, mounted in bearings on the table A, engage, as shown inFig. 20. The shaft 0 has secured upon one end thereof the lever P, bywhich it may be rotated to raise or lower the bars In one of the socketsh is placed a pencil or knife holding spindle r, to the upper end ofwhich is pivoted one end of the lever r, fulcrumed on the stand g, whichhas a forked arm to embrace the peripheral groove sin the socket-tube hwith an outwardly-projecting fin ger-receiving arm q and the latch-catchThe lever 9 projects outward beyond its pivotal connection to said standq and has pivoted thereto the latch-lever (1 the outer arm of which isforced upward by the spring (1 to cause its inner end to engage with thecatch (1 when the outer arm of the lever 'r' is depressed to raise thepencil or knife from contact with the paper or the glass plate againstthe tension of the spring 25, all as shown in Figs. 13 andla.

The'pencil is mounted in a tubular socket constructed and arranged toclamp the pencil-lead in the same manner as the well-known tubulardrawing-pencil, and is shown in elevation in Fig. 13.

In Fig. 14 the knife for cutting patterns is shown. The spindle has acylindrical hole drilled in its lower end, in which is inserted theshank u of the knife a in such a manner that it is free to revolvetherein, but will not fall out when the spindle is raised, as shown inFig. let. The knife has aninclined cuttingedge so formed that the end ofthe knife which rests upon the glass when in action is at one side ofthe axial line of the shank of said knife, so that it will automaticallymaintain a position with its cutting-edge to the front in whateverdirection it may be moved.

The pattern shown in Fig. 1 and marked 0 is for a boot-quarter; but inorder to adapt the machine to draw or cut patterns of longle-ggedboot-fronts or shoe-Vamps a modification of the supports for thepatterns is neces sary, as follows: The pattern 0 may be readilysupported by two pendent attachments to the slotted bar (3*; but if along-legged bootfront pattern or a shoe-vamp pattern is to be drawn orout three pendent supports for the pattern are necessary and the patternmust be arranged with its center line extending in the direction of itsgreatest dimension parallel to the rod 0, as shown in Fig. 18. To thisend the rod 0 is removed from the bearing in the lower part of thesleeve 0 and the rod R, having the sleeve-like hub R at one end, isfitted'in said bearing, and the rod 0 is inserted in the sleeve R andhas adjustably secured thereon thesplit sleeve R, which is secured inposition by the clamping-bolt e? and nut (2 and the vamp-pattern S orthe boot-leg pattern S (shown in dotted lines in Fig. 18) is secured tothe pendent supports 6' e and R, as shown in Figs. 2 and 18. The

rods 0 and R are prevented from turning about their axes in theirbearings by a setscrew, as T, screwed into their bearings and entering alongitudinal groove in said rods, as shown in Figs. 15 and 16.

The operation of my invention is as follows; The several parts of theapparatus being in the positions shown in Figs. 1 and 2, the firstoperation is to move the-free end of the lever P upward into ahorizontalposition, so as to move the bars N obliquely upward, and thereby liftthe bars M from contact with the glass plate L, when the paper or othermaterial to be drawn upon or out is placed in, position on the glassplate and beneath the barsM M, and then the lever 13 is returned to theposition shown in Fig. 2, when the bars Mll/I will be forced down uponthe material to be acted upon, so as to hold it firmly in posit-ion. Ifa pattern is to be drawn upon paper, the pencil and its holder 1' (shownin Fig. 13) are inserted in the tubular socket it appropriate to thesize of pattern that it is to draw, and the stand g has its forkedarmzfitted to the groove 8 of said socket, as shown in Fig. 13. If thepattern is to be cut from paper or other material, the knife to and itsholder 0, stand q, and attachments are applied to thesame socket inplace of the pencil. The pattern 0 S, or S is adjusted to the properposition above the socket-carryin g bars, and the slides E and E areadjusted 011 the bars E and F to the graduation appropriate to the sizeof pattern on the machine-i. e., at 30, if No. 5 pattern is used, or 29,if No. 4 pattern is used, as in the drawings. The truck Z is thenbrought into position, with its periphery at the bottom of its groove incontact with the pattern 0 at a suitable point, as 22. The lever g isthen disengaged from the catch g and the tension of the spring IE willcause the pencil or knife to be brought into contact with the materialto be acted upon. The operator then moves the truck Z around the pattern0 by means of the handle k in the direction indicated by the arrow onFig. 1, when the pencil or knife, if set in the tubular socket h, fittedin the bar G directly beneath the truck-carrying bar K, will describe onor cut from the paperor other material an exact duplicate in outline ofthe pattern on the machine. To draw or cut patterns of larger orsmallersizes than the pattern on the machine, the pencil or knife isplaced in the socket corresponding to the number of the boot for whichthe pattern is intended. If this were done with the slideplate B madefast or immovable, and the fulcrum-pin g removed,so that thebarE and thepencil-carrying bars would be moved about a fixed fulcrum, like theordinary pantograph, each of the differentv sizes drawn would be reducedor increased in size in a true mathematical proportion in alldirections; but as IOC the patterns for the smaller sizes do notdiminish in size in the same proportionthroughout, or, in other words,as the dimension of the pattern in the direction of the height of theboot or shoe requires to be reduced less in proportion than in thedirection of the length of the shoe, it becomes necessary to make someprovision in the machine for giving this varying proportion. Thisprovision consists in the employment of the sliding plate B connected bythe common fulcrumpin (1 to the bars D and E, the slotted extension ofthe bar D, the fulcrum-pin g, and the groove 0 in the plate B. Vvhen theplate B is free to move in the groove 0 so that the bar D will moveabout the fulcrum-ping, a pattern will be drawn or out by moving thetruck Z about the pattern 0", that isincreased or reduced in a certainproportion in the direction of the length of the rod C, and in a certainother proportion in a direction at rightangles to said rod, the amountof the variation of said two proportions being determined by thedistance from the fulcrumpin (1 at which the fulcrum-pin g is clamped tothe bar D. In certain cases it is desirable to make the leg portion ofthe pattern of a greater proportionate dimension in the direction of thelength of the boot orshoe than the foot independent of the variation inthe proportions produced by the movements of the members of thepantograph about the two fulcrum-pins d and g; and to this end thelever 1) b pin b and grooves c, c, and e are employed as follows: Whenit is desired to draw or cut a pattern of a smaller size than.the'pattern on the machine, but having a fuller leg in proportion toits height without increasing the proportion of the length of the foot,the lever 12 12 may be in the position shown in the drawings, with thepin 12 in the groove 0, or it may be adjusted to the left of Fig. 1,with the pin 12 in the groove 0. The pencil or knife is fitted to theproper socket h. The wheel Z ismoved into contact with the pattern C"sayat rand moved around the pattern in contact therewith until the point eis reached, when the lever b b is moved about its pivot by first raisingthe handle b and the pin 12 is made to engage the groove 0 whichoperation causes a movement of the plate B with the bars D E F and theother socket-carrying bars a certain distance toward the left of Fig. 1,thus adding an equal amount to the dimension of the leg in thatdirection. The operator then moves the truck Z around the pattern in thesame direction until the point r is reached, when the lever b b is movedback to its original position, and then the truck Z is moved to thestarting-point 'v to complete the pattern. The amount of variation madeby the manipulation of the lever b b may be varied by moving it so as totransfer the pin b from one groove to the next, or from the groove 0 tothe groove 0 or by moving the pin b nearer to or farther from thefulcrum-pin b, so that ing to the requirements of the case.

the angular movement of said lever necessary to transfer the pin 1) fromone groove to another will be increased or diminished, accord- Themachine, as illustrated in the drawings, is supplied with a No. 4pattern and the slides E and E are adjusted on the bars E and F to thegraduation numbered 29, which is the proper number if the patterns to bedrawn or cut are graded according to the English or American scale,where the variation between the sizes is one-third of an inch; but ifthe patterns to be drawn or out are to be graded according to the Frenchscale, in which the difference between the sizes is only aboutone-fourth of an inch, the slides E and E should be moved on the bars Eand F until they coincide with the graduations numbered 40, when, if thesame No. 4 pattern be properly adjusted to a position centrally over theseries of pencil or knife carrying bars, a series of patterns may bedrawn or cut proportioned according to the French scale. If the patternto be used on the machine should for any reason be larger or smallerthan No. 4, the slides E and E would have to be moved on the bars E andF as many divisions above or below where they are now set if Englishsizes are to be proportioned, or above or below No. 40 if French sizesare to be drawn or cut, as the pattern on the machine is sizes larger orsmaller than No. 41. It must be understood that the grad nations on thebars E and F are at a distance apart equal IOC to the distance from thecenter of one pencilcarrying bar to the center of the nextpencil-carrying bar and that said graduations are so arranged thereonand numbered that the graduations coinciding with the ends of the slidesE and E shall indicate the number of divisionson the bars E and Fbetween the pivotal connection of said slides and the center of thefulcrum-pin d and the center of the pencil-socket in the bar F,respectively. This adjustable pivoting of the bars E and F, whereby thewhole series of pencil-carrying bars may be moved bodily to greater orless distance from the fulcrum-pin 01 without changing their relationsto each other, thus rendering it possible to adapt the machine to workfrom different-sized original patterns in grading patterns to the samescale or to grade patterns to difierent scales from the same pattern, isa very important feature of my invention, and as far as my knowledgeextends is entirely new.

The machine may be adapted to draw or cut patterns for half;sizes byadjusting the pinsjand j in the proper holes in the bar K and in thestuds J and J. The studs J and J are set centrally over the bar G and inthe upper end of each are formed three holes a a and u the hole 11.being in the center and directly above the center of the bar G", thehole w being directly over the center of the space between the bars Gand G, and the hole a being directly over the center of ITO the spacebetween the bars G and G The bar K has formed therein two series ofthree holes to, w, and w arranged as shown in Fig. 17. -When the machineis adjusted as shown in the drawings, the pins j and j are passedthrough the holes 10 into the holes u in the studs; but if it is desiredto draw or cut half-sizes, said pins are passed through the holes 20 inthe bar K and into the holes 11 in the studs or through the hole w inthe bar or arm K and into the hole a in the studs J and J It will beobserved by referring to Fig. 17 that the holes in the arm K in thelongitudinal central line of said arm and that the holes in the studs Jand J are arranged in rows at right angles to said center line of thearm K, and that in making the adjustments of said arm as described theaxis of the crank-shaft in the end of the arm K will be moved a distanceequal to one-half the distance between the centers of two contiguouspencil-sockets and in the vertical plane which cuts through the row ofsaid sockets. The amount of variation in the proportion of the width ofthe boot-leg pattern to the height of the same maybe varied by adjustingthe fulcrum-pin g to a greateror less distance from the pin dindependent of the manipulation of the lever bb I claim- 1.
